Не могу получить deviceToken (didRegisterForRemoteNotificationsWithDeviceToken)?

Всем привет! Помогите, пожалуйста!
Пытаюсь сделать push-уведомления. На сервер нужно отправить логин, токен и девайс токен.
В методе didRegisterUserNotificationSettings пытаюсь сохранить deviceToken. Но у меня заходит в didFailToRegisterForRemoteNotificationsWithError.
Код прилагается
